Move bus_space_tag and bus_space_handle register access
tokens into the common isp_osinfo structure instead of being
in bus specific structures. This allows us to implement
a SYNC_REG MEMORYBARRIER call (using bus_space_barrier)
and also reduce the amount of bus specific wrapper structure
usages in isp_pci && isp_sbus.
